I've been using (VTP) VersionTracker Pro (Paid Subscription) for quite sometime now and had really like it.
That is, up until a year ago.
It's been a year now that I have had to suffer through repeated freezes (failures to respond).

Having used computers since 1994, I've always believed 2 things. 1) Never buy .0 of anything and 2) Keep your software up to date as it is continually being improved.

VTP 4.5 / 4.5.1 has destroyed my belief in #2 above, due to being less capable than it predecessor. The fact that it is slower and constantly freezes makes it basically not usable for it's intended purpose.
I have found that manually updating my software is both faster & easier than using VTP.

The company responsible for VTP should not only make repairing VTP a top priority, but should also compensate it's paid subscribers.

The current version of VTP is of poor quality & not at all stable.
I would not recommend this product at it's current inseption.
Perhaps a newer version with it's issues addressed will be forthcoming.
One can only hope so.
